• Keep this Mac on AC with lid open. Do not reboot, sleep, relaunch, accept, or expand the candidate.
• Six-hour gate no earlier than 23:11:47 EDT; fixed 24-hour gate no earlier than 2026-09-15 17:01:47 EDT.
• Only one inventory pass exists; unchanged repeat, CPU, later fresh-app, controlled-reboot, integration, and rollout gates remain pending.
• Build 22 stays queued and uninstalled; its daemon is prohibited. ISSUE-20260914-15 must not alter this frozen candidate.
